Hi Paulo,
From what I can remember in lieu of the specific educational requirements Airservices also accept previous employment as a controller. Although, I'm pretty sure you'll find with your quals it wouldn't be a problem. I've only got GCSE's and I got in, I did JATCC in 2006.
At the beginning of last year the RAAF were recruiting for ATC and I imagine that that would be an avenue worth exploring if you were looking into transferring anyway.
If I can help at all, just PM me.
Cheers now,
Spanks
